Fix 2008/03/10 |
| 1303 |
|
|
| 1304 |
|
@ Rename "force_alt_exec" keyword to "preferred_execute_handler". |
| 1305 |
|
|
| 1306 |
|
To be able to use different programs for validating execve() parameters, |
| 1307 |
|
I moved the location to specify the program's pathname from profile |
| 1308 |
|
to domain policy. |
| 1309 |
|
|
| 1310 |
|
The "preferred_execute_handler" keyword takes one pathname which is |
| 1311 |
|
invoked whenever execve() request is issued. Thus, any "allow_execute" |
| 1312 |
|
keywords in a domain with "preferred_execute_handler" are ignored. |
| 1313 |
|
This keyword is designed for validating expected/desirable execve() |
| 1314 |
|
requests in userspace, although there is no way to tell the caller |
| 1315 |
|
that the execve() request was rejected. |
| 1316 |
|
|
| 1317 |
|
@ Rename "alt_exec" keyword to "default_execute_handler". |
| 1318 |
|
|
| 1319 |
|
The "default_execute_handler" keyword takes one pathname which is |
| 1320 |
|
invoked only when execve() request was rejected. In other words, |
| 1321 |
|
this program is invoked only when the following conditions are met. |
| 1322 |
|
|
| 1323 |
|
(1) None of "allow_execute" keywords in the domain didn't match. |
| 1324 |
|
(2) The execve() request was rejected in enforcing mode. |
| 1325 |
|
(3) "preferred_execute_handler" keyword is not used by the domain. |
| 1326 |
|
|
| 1327 |
|
This keyword is designed for handling unexpected/undesirable execve() |
| 1328 |
|
requests, to redirect the process issuing such requests to somewhere. |
| 1329 |

Fix 2008/03/18 |
| 1331 |
|
|
| 1332 |
|
@ Fix wrong/redundant locks in pre-vfs functions. |
| 1333 |
|
|
| 1334 |
|
lock_kernel()/unlock_kernel() in pre_vfs_rename() were redundant for |
| 1335 |
|
2.6 kernels. |
| 1336 |
|
|
| 1337 |
|
Locking order in pre_vfs_link() and pre_vfs_unlink() for 2.4 kernels |
| 1338 |
|
after 2.4.33 were different from before 2.4.32 . |
| 1339 |
|

Version 1.6.0 2008/??/?? Feature enhancement release. |
